Lab Gas Nitrogen Generators

CGTCompressed Gas Technologies Inc. nitrogen generators cover a wide range of flows and purities to exactly match the needs of applications including LCMS, GC, ICP, ELSD / CAD detector, Circular Dichroism and Sample Evaporation. The optional Generators incorporating an integrated oil free compressor completely eliminate any reliance on a house compressed air supply giving complete security of supply.
The technology used to procure a continuous flow of high purity nitrogen is pressure swing absorption ( PSA ). This technique uses one or two carbon molecular sieves beds (CMS) to eliminate oxygen and other contaminants in the ambient air selectively.

How Lab Gas Nitrogen Generators Work

The technology used to produce a continuous flow of high purity N2 How Lab Gas Nitrogen Generators Work is pressure swing adsorption (PSA). This technology uses a combination of molecular sieves to selectively eliminate O2 and other contaminants in the ambient air. The CMS column(s) alternate between the purification and regeneration modes to ensure continuous N2 production. The gas generator is designed to take pre-filtered compressed air at 7 or 8.5 barg (102 or 123 psi g) (depending on model) from the existing laboratory supply or via the integrated oil-free compressor.
This flow of filtered compressed air then passes through the CMS column which is in the purification mode. At this point, the O2, CO2, humidity and hydrocarbons are eliminated from the compressed air, producing a flow of clean and dry high purity nitrogen. For zero N2 generators, a heated catalyst oxidizes additional hydrocarbons from the N2 gas flow providing zero grade N2 with a remaining hydrocarbon content of <0.1ppm.
